Detailed Description

\inmodule QtGuiPrivate \inheaderfile rhi/qrhi.h

Since
6.6

Describes the layout of vertex inputs consumed by a vertex shader.

The vertex input layout is defined by the collections of QRhiVertexInputBinding and QRhiVertexInputAttribute.

As an example, let's assume that we have a single buffer with 3 component vertex positions and 2 component UV coordinates interleaved (x, y, z, u, v), that the position and UV are expected at input locations 0 and 1 by the vertex shader, and that the vertex buffer will be bound at binding point 0 using \l{QRhiCommandBuffer::setVertexInput()}{setVertexInput()} later on:

QRhiVertexInputLayout inputLayout;
inputLayout.setBindings({
{ 5 * sizeof(float) }
});
inputLayout.setAttributes({
{ 0, 0, QRhiVertexInputAttribute::Float3, 0 },
{ 0, 1, QRhiVertexInputAttribute::Float2, 3 * sizeof(float) }
});
